Lightweight Portable Security (LPS)-A Linux disto from the US Department of Defense

WEBINAR:On-Demand

"the Lightweight Portable Security distribution was created by
the Software Protection Initiative under the direction of the Air
Force Research Laboratory and the US Department Of Defense. The
idea behind it is that government workers can use a CDROM or USB
stick to boot into a tamper proof, pristine desktop when using
insecure computers such as those available in hotels or a worker's
own home. The environment that it offers should be largely
resistant to Internet-borne security threats such as viruses and
spyware, particularly when launched from read-only media such as a
CDROM. The LPS system does not mount the hard drive of the host
machine, so no trace of work activity can be written to the local
computer."
